1. What is a Board Feet In A Log Calculator?

Definition: This calculator estimates the volume of lumber in board feet that can be obtained from a log based on its diameter and length.

Purpose: It helps forestry professionals, sawmill operators, and woodworkers estimate lumber yield from logs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( BF \) — Board feet (volume measurement)
• \( D \) — Log diameter (inches at small end)
• \( L \) — Log length (feet)

Explanation: The formula accounts for the taper of the log by subtracting 4 inches from the diameter and squaring the result.

3. Importance of Board Feet Calculation

Details: Accurate board feet estimation is crucial for lumber pricing, inventory management, and project planning.

4. Using the Calculator

Tips: Enter the log diameter (measured at the small end) in inches and log length in feet. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why subtract 4 inches from the diameter?
A: This accounts for the natural taper of the log and sawing kerf (waste from the saw blade).

Q2: How accurate is this formula?
A: It provides a rough estimate. Actual yield depends on log quality, sawing method, and other factors.

Q3: What's considered a standard board foot?
A: 1 board foot = 1 foot long × 1 foot wide × 1 inch thick (or equivalent volume).

Q4: Does this work for all tree species?
A: The formula works generally, but some species may have different conversion factors.

Q5: How do I measure log diameter?
A: Measure the inside bark diameter at the small end of the log.
